A diet rich in fruit and vegetables can be effective in the reduction of oxidative stress, through
the antioxidant effects of phytochemicals and other mechanisms. Protection against the …

We have undertaken a randomized trial to confirm the ability of a class of phenolics,
flavonoids, to increase urinary anti-mutagenicity in smokers. Ninety heavy smokers were …

Cruciferous vegetables contain compounds with antioxidant properties (eg carotenoids,
vitamin C and folates) and can alter the activity of xenobiotic metabolism (ie …

The effect of dietary intake of flavonols (predominantly quercetin) on oxidative DNA damage
was studied in thirty-six healthy human subjects (sixteen men, twenty women). The study …

Consumption of fruits and vegetables has been associated with a decrease in cancer
incidence and cardiovascular disease, presumably caused by antioxidants. We designed a …

Summary Background & Aims: Epidemiological studies suggest that antioxidant polyphenols
in the human diet may protect against diseases such as cancer. In this study we investigated …

Phytochemicals may protect cellular DNA by direct antioxidant effect or modulation of the
DNA repair activity. We investigated the repair activity towards oxidised DNA in human …

Flavonoids are a large group of phenolic compounds found ubiquitously in plants and
consumed as part of the human diet. They are known to be potent antioxidants, free radical …

Diets rich in fruits and vegetables are associated with lower risk of cancer which may be
conferred in part by the antioxidant properties of these foods. However, antioxidant …

Berry extracts possess antioxidant activity in cell free systems, whereas cell culture and
animal experimental systems have produced mixed outcomes. Our aim was to investigate …
